Mike Dunleavy, Governor of the State of Alaska, proclaimed Alaska Invasive Species Awareness Week (June 9-15, 2024), encouraging all Alaskans and visitors to learn about, prevent, report, and contribute to control of invasive species in the state.

In the spring of 2023, the AKISP Board and Membership approved the 2023-2028 AKISP Strategic Plan. This plan is the culmination of a multi-year effort to frame goals, strategies, actions, and evaluation measures which intend to guide Partnership members activities and collaboration at statewide, regional and local levels. Many agencies and organizations participated in identifying priorities for future invasive species work in Alaska.

Biological invasions are a major threat to ecosystems, biodiversity, and human well-being, resulting in ecosystem degradation and causing economic costs in the multi-trillions of euros globally. A study led by McGill University sheds light on the stark economic cost resulting from biological invasions in the European Union (EU). Most invasive alien species are not adequately assessed for their actual and potential economic impacts therefore most cost estimates are grossly underestimated, say the researchers. To fill this gap, the team quantified the economic costs of biological invasions to the European Union, while estimating future invasion costs using predictive models.

The new (Alien Species) Regulations 2022 recently passed by Cabinet will ensure greater protections for Cayman's most precious native flora and fauna (plants and animals) with the creation of a prohibited species list, and differentiating between domestic & feral species. The legislation also provides ways to control feral and alien species, crucial to reducing threats to both pets as well as our native species.

Antarctic tourists and scientists may be inadvertently seeding the icy continent with invasive species, a new study says. Foreign plants such as annual bluegrass are establishing themselves on Antarctica, whose status as the coldest and driest continent had long made it one of the most pristine environments on Earth.

For homeowners or landscapers in Michigan looking to plant small to medium flowering trees this spring, consider these alternatives to Callery pear.

A species of exotic tick arrived in Ohio in 2021 in such huge numbers that their feeding frenzy on a southeastern farm left three cattle dead of what researchers believe was severe blood loss. The scientists from The Ohio State University have reported in the Journal of Medical Entomology on the state’s first known established population of Asian longhorned ticks, and are now conducting research focused on monitoring and managing these pests.

Ohioans are encouraged to help with research efforts: People who think they’ve spotted an Asian longhorned tick can email ticks@osu.edu for instructions on how to collect the specimen and send it to Ohio State scientists as part of ongoing surveillance. To date, the lab has received Asian longhorned ticks from residents of 11 Ohio counties. More information about spotting Asian longhorned ticks and preventing tick exposure is available on Ohio State’s Bite Site hosted by the College of Food, Agricultural, and Environmental Sciences Knowledge Exchange.

Invasive insect and arthropod species make for a lot of scary headlines—think emerald ash borer, spotted lanternfly, and Asian longhorned tick, just to name a few. But success stories in invasive-species response are out there. They just need to be told. One of those success stories is the eradication of the European grapevine moth (Lobesia botrana) in northern California after it was found there in 2009. A cooperative, multipronged response effort kept infestations from running wild, and it was declared eradicated in 2016, two years after the last adult moth was caught in the region. The story of this effort is recounted, along with analysis of the invasion’s dynamics, in a study published in January in the Annals of the Entomological Society of America.
